My shed/summerhouse is so special because it was designed by my husband and I and my husband built it from scratch, it is a sanctuary from everything, it is so quiet and relaxing. I use it for my home business as well as storage of my products and sometimes just to go and spend some quiet time down there.
It is fully insulated, has electrics, telephone and even a TV point. It is double glazed so warm in the winter but double doors open onto the garden for the summer. It has lovely stripped wood flooring and PVC cladding on the inside for easy cleaning.
